The National Salary Comparison is a unique guide to how the differences in local pay levels, tax and cost of living between countries affect the mobility management options of employers.  This compares the relative buying power of managers in 58 countries, showing at a glance whether an individual's spending power would be maintained if they moved to work in a different country and were paid a local salary.  

It provides a big-picture pointer to issues that many arise when developing remuneration policies for permanent international transfers, remote international working and international assignments on local terms.
